The 27-year-old Hurd did what Miguel Cotto, Canelo Alvarez, Erislandy Lara and Jermall Charlo could not after the ringside doctor stepped in to stop the bout following a brutal closing 20 seconds of the 10th frame.

The Accokeek, Md., native often neglected defence in the early rounds and fought back after a slow start to wear down the toughest opponent of his career. The championship affair shifted in the sixth as Trout tired and Hurd picked up his output of power shots despite a bloody cut over his left eye. Trout was practically saved by the bell in the 10th round and trainer Louie Burke did not protest as he was advised that the fight should be stopped.

“It’s most definitely tougher to defend the title than win it,” Hurd said. “I’m always the one that comes on stronger at the end of the fight. We knew we were going to wear Austin Trout down in the later rounds and eventually stop him. My cut made me a little better with my head movement.

“Team Swift, we don’t run from anyone. I’m ready to unify. 2018 is the year for unifications. It doesn’t matter who it is. I’m ready to fight anyone.”

Hurd had a 89-31 edge in power punches landed over the last three rounds and connected on 43 percent of his power shots over 10 rounds.
